5 clam (ci. 13s-sz) The invention pertains to heddle supporting framesand its general aim is to facilitate the removal and replacement ofheddles relative to the frame.

More specifically stated, the invention contemplates the provision of anovel and advantageous mounting for the bars upon Which`the heddles aresupported in the frame, permitting easy disassociation of the bars fromthe frame and presenting no obstruction to the movement of the heddlesalong the bar.

The objects of the invention thus generally stated, together with otherand ancillary advantages, are attained by the construction andarrangement shown by way of illustration in the accompanying drawingsforming a part hereof, in which: Figure 1 is a side elevational view ofa heddle supporting frame embodying my invention.

Fig. 2 is a fragmentary elevational view on an enlarged scaleillustrating especially the improved means for mounting the heddlesupporting bar in the frame.

Fig. 3 is a cross sectional view taken approximately in the plane ofline 3 3 of Fig. 2.

This application is a division oi' my copending application Serial No.514,313, led December 15, 1943, now abandoned.

The heddle frame comprises briey, top and bottom rails I and II,preferably of wood, and end members I2 eac-h comprising a pair ofgenerally U-shaped metal straps I3 and I3 having yoke portions weldedtogether providing parallel end portions I4 spaced apart to receivebetween them the ends of the rails Ill and II, such end portions beingsuitably secured to the rails.

The present invention concerns the mounting of a heddle supporting baror bars I5 within the frame so as to permit 'movement of the heddlesalong the bar without obstruction by the supporting devices. Moreover,the construction is such as to permit of lateral deection of the ends ofthe bars whereby the heddles may be removed from the bars, and to permiteasy removal of the bars from the frame with or without the heddles. Ingeneral, each of the supporting bars is releasably secured at itsopposite ends to the end members I2 by means of latch devices I6 formingthe subject of my said application, Serial No. 514,313. Intermediatetheir ends the bars are supported from the 'adjacent rails I0 and II oi"the frame by means of one or more anchoring devices generally designatedI'I.

The heddle supporting -frame is designed forA use with heddles It havinghooks I9 at opposite ends, and the heddle supporting bars Il aregenerally channel shaped in cross section. Thus each provides one legforming a narrow wall or heddle ilange III with a free edge portionexposed for engagement by the heddle hooks I9 and the other legextended'to form a relatively wide anchoring member connected to theadjacent side railby one or more anchoring devices Il, two

such devices being herein employed in the case of each rail.

, In general, the latch devices I6 may comprise a detent member in thenature of a slide bolt 21 mounted for sliding movement transversely ofthe end member I2 and engageable in an end opening recess formed by thechannel-of the supporting bar to hold the latter in normal position. Asshown, the slide bolt is inv the form of a iiat plate slidable in theend member I2 o! the frame and having its inner end position enteredbetween the legs 2li and 2I of the'bar. The plate is mounted on theupper end of a leaf spring 2! anchored to the outer side of the endmember I2. The spring is yieldable inthe. plane of the frame for thepurpose of permitting the movement of the slide bolt outof the channel,and the bolt carries a transverse lug 3U for holding the bar in itsdeflectedposition, the device having been released and restored' to`normal position after deflection of the bar. The slide bolt 2l isapertured to receive slidably a bent upper end portion of the spring andthe spring is yieldable transversely of the frame to permitdisengagement of a U-shaped latch member.3I normally engaging withoneedge portion of the end member to hold the bolt against accidentalwithdrawal from the heddle supporting bar.

" In the present preferred embodiment of the invention, each anchoringdevice comprises a rod 32 extending through a hole 33 in the rail andhaving a connection with the bar disengageable by a short movement ofthe bar relative to the rod and'including in the present embodiment ahook 3l. The outer end of the rod is threaded for reception of a nut 3iclamped in position in a recess in the rail by a plate 3'6, the latterengaging a collar Il on the nut. By a rotational adjustment of the nut3F the position 'of the rod 32 relative to the rail may be adjusted asmay be desirable to compensatefor any bowing of the rail.

The hook u of the rod l2 is secured to the supporting bar along theupper edge thereof and therefore in overlying relation to the-channel.The upper edge of the bar is formed with transverse flanges Il carryinglugs 4I shaped to form loops or, open ended sockets for receiving thehooks (Fig. 3) Each hook u is preferably formed with a flat sideengaging the flange Il Ato hold the bar against turning. The lugs Il aremade relatively short so that with the one end of the bar shiftedlaterally clear o! the end member I2, the bar need be movedlongitudinally only a short distance to disengage it from the hooks 3l.

It will be observed that by the construction provided for supporting theheddle bars in the frame, the heddles may be moved along the barswithout interference or obstruction by the anchoring devices Il.Moreover, when desired the heddles may be removed from the bar or newheddles placed thereon simply by releasing the bars at one end fromtheirconnection with the frame and swinging such ends laterally into adeflected position at one side oi' the frame, the bars being held insuch deflected positions by the lugs as shown in Fig. 3. Theconstruction also permits removal of the bars from the frame with orwithout the heddles on the bars, and this by simply releasing the latchdevices Il at one end of the bars and imparting a short endwise movementto the bars after swinging the released lends into. deflected positionsat the side of the frame, the length of the disengaging movement beingdetermined by the length of the hooks. on the anchoring devices.

I claim as my invention:

. 1. A heddle frame comprising top and bottom rails and end membersconnecting said rails, heddle supporting means carried by the frameincluding a bar, an anchoring device carried by one of said rails andhaving a connection with said bar intermediate the ends thereof andmeans connecting the ends of the bars to said end members including alatch device carried by one of the end members and disengageable fromone end of the bar to permit lateral deflection of the bar out of theplane of said end member,

the connection between said bar and the anchor- 'v ing devicepermittingdisengagement of t-he bar from the device by moving the bar a shortdistance endwise when the said one end thereof is deflected out of theplane of the end member.

2. In a heddle frame having a side rail and an end member perpendicularthereto', a heddle supporting bar having a free end terminating adjacentthe inner side of said end member, a latch,

the bar disengageable by a short movement of the bar longitudinally whensaid free end occupies its deflected position.

3. In a heddle frame having a 4side rail and a pair of end,A membersperpendicular thereto. a heddle supporting bar, and an anchoring devicefor supporting the rod intermediate the ends thereof. said anchoringdevice comprising a rod projecting from the inner edge of the side railand having a portion extending longitudinally of the rail in spacedrelation thereto, said bar being of channel shape to provide a heddlesupporting leg and a bar supporting leg, a. nange at the upper edge ofthe'lbar supporting leg extending laterally above the channel, and a lugon said flange shaped to form an open ended socket lfor receiving saidend portion of the rod.

4.
